Answer:
Step-by-step explanation:
10+10=20
8+8 = 16
36 is perimeter of the rectangle
diameter of half circle is 8
formula for circumference of a circle is r π = 8 x 3.14
8 x 3.14 = 25.12 but your not done yet its a half circle so divide by 2
25.12/2 = 12.56
12.56 + 36 = 48.56 is final answer
give me brainliest
Multply both equations by 2 leaving
x + 2y = 8
x - 2y = -2
Add the equations giving
2x = 6
x = 3
Substitute 3 in the top equation
3 + 2y = 8
2y = -5
y = -2.5
K is equal to -69.5 K=69.5 You put it in an equation 47.9-K=-21.6Then you subtract 47.9 from both sides and you get K=69.5
Answer:
36 since they are similer triangles
Longer process:
24/24 = 36/x
solve this and you get 36
1.06
1.501
1.506
1.605
